BROOTS

The original six-minute "pilot" featured a slightly different version of Might Orbots called Broots (pronounced "Brutes"). Rob and Ono looked similar to their 'finished' selves, though definitively more late 70s-like. The Orbots, while having the same names as in the finished product, are subtly different, and obviously unfinished. Even their combined form aka "Super-Broots" would go through some more developmental evolution before becoming Mighty Orbots.
